摘要
应用肾上腺素自体氧化法对肺癌、肺结核患者和健康者外周血红细胞超氧比物歧化酶（ＳＯＤ）活性进行测定，结果显示肺癌组ＳＯＤ活性较肺结核组以及健康组明显降低（Ｐ＜０．００１）。若以ＳＯＤ活性值＜３０Ｏｕ／ｍｌ为肺癌诊断阳性标准，则本法对肺癌敏感性为９０％，特异性为８５％，诊断效率为８７．５％，误差值为１０．５％。
The SOD activity of red blood cells in circulating blood was determined by the adrenaline sulf-oxide method in patienu with carcinoma of lung,in patients with pulmonary tuberculosis and in healthy persons.Results indicated that the SOD activity was significantly decreased in the group of patients with carcinoma of lung than in the group of patients with tuberculosis and in group of healthy persons(P<0.001).If SOD activity value less than 30μ/ml is taken as positive standard for diagnosis of carcinoma of lung,the sensitivity of the method is 90%;the specificity,85%;the diagnostic efficiency,87.5%; ertor value,10.5%.
